SPECIFICATION forming part of Letters Patent No. 377,064, dated January3l. 1889- Application lile1lAug\ist5,1BS7. Serial No. 246,235.

To @ZZ whom t 4may concern:

Beit known that i, SARAH M. CLARK, of Milwaukee, in the county ofMilwaukee and State of XVisconsin, have invented new and usefulImprovements in Dough -Mixing Machi n es; and I do hereby declare thefollowing to be a full, clear, and exact description of said invention,reference being had to the accompanying drawings, and to the letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in dough-mixers.

The object of my invention is to provide al device for stirring andmixing flour and other ingredients used in making cake, bread, Sie.; andit pertains to the peculiar combination and arrangement of themixing-fork, the gears for increasing the movement of the mixingfork,the gearsnpporting bracket, and the mechanism for fasteningdough-receptacles of different sizes to a su pporting-base.

The construction oi' my invention is explained by reference to theaccompanying drawings, in which- Figure 1 represents a side view of themixer and doughlreceptacle in position for use. Fig. 2 represents afront View of the device drawn at right angles to that shown in Fig. l.Figs. 3 and 4 are details.

Like parts are represented by the same reference-letters throughout theseveral views.

A is the supportiug-base,to which the doughreceptacle B is rigidlyattached by the retaining-hooks C and D, and also to which thegearsupporting bracket E is riwidl y secured by bolts F F.

G is the mixingforks, by which the ingredients to be used are mixedtogether. Motion is communicated to the mixing-fork from the handle Hthrough the shaft I, beveled gears J and K, and shaft L. The lower endof the shaft L is enlarged and provided with a slot, M, for thereception of the shank N of the mixingfork. Vhen the shank N is insertedin the slot M, it is secured in place by the pin O. The supportingbase Ais provided upon its respective sides with a series of apertures, P I?,for the reception of the lower end of the retaining-hooks C C. Infastening the receptacle B the ends of the hooks C are first (No model.)

inserted through the keepers RR upon opposite sides of the receptacle,and from thence into one of the apertures P. The opposite ends of thehooks C are secured to the base A by Staples S S. Thus it will be seenthat when the hooks C are inserted through the keepers R and into theapertures P they are held firmly in place at both of their ends, wherebythe ren ceptacle B is held firmlyin place. The number of apertures I?used corresponds with the different sizes of receptacles B used. Viheu alarge receptacle like that shown iu Fig. 1 is used, the hooks C passthrough the keepers R into two outer apertures. Vhen asmaller receptacleis used, as shown in Fig. 2, the same hooks Gare inclined centrallyinward and engage in the two inner apertures, P, as shown in Fig. 2,whereby it is obvious that the same hooks C, though secured at fixedpoints at their outer ends by the staples S, may be inclined inward andoutward to conform to the various sizes of receptacles used. In additionto the hook C, when a thick dough is being mixed, I preferably use thehooks D D, which are also secured to the base A by said hook-retainingstaples S, while they engage at their upper ends upon the upper edge ofthe receptacle B against the sides of the handles T, whereby themixing-cans are held more firmly in place and prevented from turningwith the mixing-fork. rIhe tines a of the mixing-fork G are preferablyformed of heavy wire or light iron rods bent in a U shape, as shown inFig. 3, having central U-shaped portion of the tines cdownward, and thetwo upper ends of the tines rigidly secured tothe cross-head U of themixingfork, whereby the respective sides of said U- shaped tinesmutually strengthen and support each other, and the fork is therebycapable of greater resistance than it would otherwise be were the tinesmade single instead of double, as shown in Fig. 4. The mixing-fork shownin Fig. 4 is a modied form, having mixing tines upon one side of itscenter only. This form of fork is adapted to be used in a largereceptacle, as the circle described by its rotary movement conforms tothat of the inner wall of the receptacle, and it is obvious that theentire contents of the large receptacle may by its use be stirred, whilethe resistance of such mixing-fork is much less than that of the largerIOO Io end to said base A by staples S, and their oppofork whichconforms in width to the diameter of the larger receptacle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a dough-mixing machine, the combination of the base A, providedwith series of apertures I P, receptacle B, provided with keepers R R,retaining-hooks C, secured at one site ends being adapted to be insertedthrough the keepers B and into one of the several apertures P, andbracehooks D, secured at their lower ends to said base A by said staplesS, 'and adapted to engage at their upper ends upon the upper edge ofsaid receptacle B, whereby said receptacle is held firmly in place uponsaid base A, substantially as and for the purpose specified. y i

2. In a doughmixing machine, the combination of the receptaclesupportingbase A, provided with series of apertures P P, receptacle B, providedwith keepers B B, retaininghooks C C, secured at one end to saidplatform or base A, and adapted to be inserted through 25 said keepers Rand into one of the several apertures P, gear-supporting bracket E,rigidly affixed at its lower end to said base A` and adapted to supportthe mixing-fork and fork rotating mechanism centrally above said re- 3oceptacle B, mixing-fork G,and the fork-rotating mechanism, allsubstantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

SARAH M. CLARK.
